2 Claims. (CI. 20-11) This invention relates to a window frameconstruction and more particularly to a construction of the window sill.

In the conventional construction of a double-hung window frame or otherwindow frames of the same general type, the brick mold rests on aprojection of the sill called a sill. It has not been practical to makemultiple window units by placing single window units together becausethe sill lug which projected beyond the back of the window jambs had tobe cut off. This cutting removed the greater part of the still which,because of its being an end grain, is most effectively treated withtoxic preservative treatment. An alternative to this has been to makemultiple window units using a long one-piece continuous window sillrunning under the combined window frame units. The use of the longone-piece window sills is objectionable because they have a greatertendency to twist and warp than do short window sills and in additioncreate a stocking problem for the dealer.

An object of this invention is to provide a new and improved windowframe construction wherein an outer section of the sill has extensionswhich are of a length so as to terminate flush with the back of thejambs and a brick mold associated with each side jamb of the Window hasa stepped lower end so that a part thereof rests on the associated sillextension and another part encloses the end of the extension and fillsthe sill out to full width.

Another object of the invention is to provide a window frameconstruction comprising spaced apart side jambs, a window sill having awindow underlying section extending between the jambs, an outer sectionof the sill integral with the first section and having extensions beyondthe ends of said first section so as to terminate flush with the back ofthe jambs, a blind stop associated with each jamb, and having its lowerend seated on one of said extensions, a brick mold associated with eachblind stop having a stepped lower end so that a part thereof rests onthe associated sill extension and another part encloses the end of theextension and fills the sill out to full width.

A further object of this invention is to provide a preformed window sillconstruction for optional use,

without cutting, in either a single window unit or in a multiple windowunit each of which has spaced apart side jambs wherein the window silldoes not require any cutting on the job and adjacent side jambs in amultiple window unit may be positioned in back to back contact.

Another object of the invention is to provide a preformed window sillfor use in either a single window construction or in a multiple windowunit without any cutting of the sill wherein the window sill comprises afirst window underlying section adapted to extend between a pair ofspaced apart side jambs and an integral outer section having extensionsbeyond the ends of said first section of a length sufiicient toterminate flush with the back of said side jambs, whereby the sill maybe used in a single window construction or may be placed end to end withat least one other sill in a multiple window unit and with adjacent sidejambs in back to back contact.

The objects of the invention generally set forth, together with otherancillary advantages, are attained by the construction and arrangementshown by way of illustration in the accompanying drawing, in which:

Fig. 1 is a fragmentary view in elevation of a single windowconstruction embodying the invention;

Fig. 2 is a fragmentary front elevation of the construction shown inFig. l and more particularly the lower left corner thereof on anenlarged scale with the window sash and building wall removed;

Fig. 3 is a perspective view of the window construction shown in Fig. 2;

Fig. 4 is a horizontal section taken along the line 4--4- in Fig. 2;

Fig. 5 is a fragmentary view in front elevation of a multiple windowunit with the window sash removed; and

Fig. 6 is a horizontal section taken along the line 6-6 in Fig. 5.

While this invention is susceptible of embodiment in many differentforms, there is shown in the drawing and will herein be described indetail an illustrative embodiment of the invention with theunderstanding that the present disclosure is to be considered as anexemplification of the principles of the invention and is not intendedto limit the invention to the embodiment illustrated. The scope of theinvention will be pointed out in the appended claims.

A single window construction embodying the invention is illustrated inFig. 1 wherein the window is mounted in a building wall, indicatedgenerally at It, and comprises a head 2 and window sill 3 which areconnected by vertically extending spaced apart side jambs one of whichis indicated at 4 in Figs. 3 and 4. Upper and lower window sash 5 and 6,respectively, are slidably mounted in the window frame.

The single window construction is shown in greater detail in Figs. 2, 3,and 4. The jarnb 4 has a spring type Weatherstripping member '7 in whichthe window sashes 5 and 6 are slidably mounted and the jamb is mountedin a wall construction which, as shown, may be composed of studs, one ofwhich is indicated at 8. Rock lath 9 and plaster it form the inner sideof the wall. Sheathing 11 and siding 12 form the outer weather side ofthe building wall.

As illustrated in Fig. 4, the window sill 3 has a window underlyinginner sill or section 13 which at its end 13a fits into a grooveprovided in the lower end of side jamb 4, and a outer sill section 14 ofthe window sill 3 is formed integral with the section 13. The outersection 14 is longer than section 13 and is of a length sufiicient toterminate flush with the back of the side jamb 4 to provide a base uponwhich a blind stop 15 may be seated.

A brick mold 16 overlaps the blind stop 15 and the sheathing 1i andextends between the head 2 and window sill 3. The lower end of the brickmold 16 is stepped so that a part 17' rests on the outer section 14 ofthe window sill and another part 18 extends down and laps the end orextension of the window sill section 14 to enclose the end thereof andextend the window sill section out to full length. The part 13 of thebrick mold has a groove 19' on its underside which continues the dripgroove machined on the underside of the window sill section 14.

An important feature of my invention is that the win dow sill 3 may bepreformed and treated and is optionally usable without cutting either ina single window construction, as described above, or may be used inmultiples to form the window sill of a multiple window unit, this beingillustrated in Figs. 5 and 6.

As shown in Figs. 5 and 6, a pair of adjacent side jambs 2t and 21 areplaced in back to back contact and are grooved to receive the ends 24and 25 of window underlying inner sill sections 22 and 23 of windowsills indicated generally at 26 and 27, respectively. The outer sillsections 28 and 29 of the window sills 26 and 27 respectively abut eachother at their ends as indicated at 3% to form a continuous window silland a rnullion cornposed of a blind stop 31 and a casing 32, may extendupwardly from the outer sections 28 and 29 of the window sill tocomplete the window construction.

The use of the new window sill construction avoids cutting on the jobwhich heretofore has been required to cut the usual sill lugs whichleaves a window sill with rough cut ends and removes the end grainportion of the window sill member which has usually been previouslytreated with a toxic preservative.
